- Measure resistance between terminals of valve.
Specified value: 25 to 35 Ohms

If specified value is not obtained:
- Replace recirculating valve for turbocharger -N249-.
- Erase DTC memory of Engine Control Module (ECM), Diagnostic mode 4: Reset/erase diagnostic data. Diagnostic Mode 4: Reset/Erase Diagnostic Data
- Generate readiness code. Monitors, Trips, Drive Cycles and Readiness Codes

If specified values are obtained:
- Connect test box to control module wiring harness. Test Box, Connecting For Wiring Test







- Check wire between test box socket 105 + 2-pin connector terminal 2 for open circuit according to wiring diagram.
Wire resistance: max. 1.5 Ohms
- Check wire for short circuit to B+ and Ground (GND).

If no malfunctions are found in wire:
- Check wire between 2-pin connector terminal 1 and the Fuel Pump (FP) Relay -J17- for open circuit according to wiring diagram.
Wire resistance: max. 1.5 Ohms

If no malfunctions are found in wires:
